Working Memory

Working Memory

Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this information.

Higher Mental Functions of Brain: Learning and Memory

Higher Mental Functions of Brain: Learning and Memory

Memory is one of the most vital higher mental functions of the brain. Memory is closely related to learning because it enables us to retain information and experiences from our past to use them in our present life. It also helps us to remember facts, events, and skills, such as riding a bike or swimming. There are two types of memory — declarative memory, which involves memorizing facts or events, and procedural memory, which enables us to remember how to do something like writing or playing an...

Biological Influences on Intelligence

Biological Influences on Intelligence

Intelligence is often thought to be linked to brain size, but the relationship is more complex than that. While brain size does correlate modestly with some abilities, like verbal skills, the connection is weaker for others, such as spatial reasoning. Other factors, like brain structure, also play crucial roles. For instance, despite Einstein's smaller-than-average brain, his parietal cortex, which is involved in spatial reasoning, was 15% wider, suggesting that neural density might matter more...

Brain Imaging

Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).

Information Processing Approach

Information Processing Approach

The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is also...

Neuroplasticity

Neuroplasticity

Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.

Summary

Working memory training significantly boosted fluid intelligence and altered brain activity patterns, including neuroelectric and hemodynamic responses. These changes suggest enhanced working memory functions and potentially improved long-term memory processes.

Area of Science:

Cognitive Neuroscience
Neuroplasticity

Background:

Working memory (WM) plays a crucial role in cognitive functions.
Understanding the neural mechanisms underlying WM training is essential for cognitive enhancement.

Purpose of the Study:

To determine if working memory (WM) training enhances fluid intelligence.
To investigate the effects of WM training on neuroelectric (EEG) and hemodynamic (NIRS) brain activity patterns.

Main Methods:

A parallel-group experimental design was employed.
Participants underwent 30 hours of either WM training or communication training (active control).
Neuroelectric (EEG) and hemodynamic (NIRS) brain activity were measured.

Main Results:

The WM training group showed significant improvements in fluid intelligence tests.
Neuroelectric activity revealed changes in theta and alpha bands, with synchronization and desynchronization patterns observed.
Hemodynamic activity shifted towards balanced frontal activation, indicating changes in brain network engagement.

Conclusions:

Working memory training effectively enhances fluid intelligence.
WM training induces significant alterations in both neuroelectric and hemodynamic brain activity.
These neural changes suggest improvements in WM maintenance, central executive functions, and potentially long-term memory processes.
